I have a question about step 1 on the recipe "Riz Au Lait" from Oui, Chef. It says:

"Place the rice in a medium saucepan, cover with water and bring to a boil. Stir the rice a few times to knock any starch loose, then pour the rice through a strainer, run under warm water to rinse, and place back in the pan. Add 1 cup of the cream, the 2 cups of milk and the vanilla seeds and pods. Bring to a boil over medium -high heat, then lower to a simmer and cook for 30 minutes, stirring occasionally. Add the 1 cup sugar, stir and cook for an additional 10 minutes. Remove the vanilla pods before serving." How much sugar?
